SAW.

SPECIFICATION forming part of Letters Patent No. 391,843, dated October30, 1888.

Application filed April 2, 1888. Serial No. 2693246 To all whom it mayconcern.-

Be it known that 1, WILLIAM G. GRAY, a citizen of the United States,residing at New Amsterdam, in the county of Harrison and State ofIndiana, have invented certain new and useful Improvements in Saws; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention has relation to improvements in wood-saws, and to thatclass known as gullet-saws, and it consists in the peculiar formation ofthe teeth and gullet, as will behereinalter more fully set forth andclaimed.

In the accompanying drawi ngs, Figure 1 represents my improved saw inside elevation, and Fig. 2 is a plan view of the same to show the teethunset.

Referring by letter to the said drawings, A indicates a saw-blade, whichmay be of steel or other suitable material; and B indicates the teeththereon, which are of a peculiar construction. These teeth pitch from acentral point, C, in opposite directions, and are filed down in thegullet on alternate sides of each tooth. It will be observed that one ofthe lon No model) gitudinal sides of each tooth is plain and ap;proximately straight, while the opposite longitudinal side (611218 aswecpi ng curvature, and is also filed from the base to or near thepoint, so as to present a clearing or cutting edge, I). To this featureof construction I attach considerable importance, as it will be seenfrom the set and form of the tooth the kerf maybe always kept clear.

Having described my invention, whatl claim 1s The saw-blade A, havingthe teeth pitched in opposite directions from a central point, as shown,each tooth having one of its longitudinal edges plain or straight, andthe opposite edge a having a sweeping curvature, alternate edges (4being tiled on opposite sides, as at b, from the point to the base, andthe gullet or base of each tooth being also filed on alternate sides,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM C. GRAY.
